To study the concentration effects of the bacterium Winogradskyella sp. on amoebic gill disease (AGD), Atlantic salmon Salmo salar were pre-exposed to 2 different doses (108 or 1010 cells l-1) of Winogradskyella sp. before being challenged with Neoparamoeba spp. Exposure of fish to Winogradskyella sp. caused a significant increase in the percentage of AGD-affected filaments compared with controls challenged with Neoparamoeba only; however, these percentages did not increase significantly with an increase in bacterial concentration. The results show that the presence of Winogradskyella sp. on salmonid gills can increase the severity of AGD. © Inter-Research 2006.
